The U.S. Bureau of Land Management office in Utah on March 25 issued a finding of no significant impact based on a recent environmental assessment of a power project of Utah Associated Municipal Power Systems (UAMPS).
UAMPA had applied in June 2014 for a right-of-way (ROW) that would be used to construct a waste heat recovery facility on land near Veyo, Utah, that is managed by BLM. UAMPS proposes to construct and operate a heat recovery power facility adjacent to the existing Kern River natural gas line compressor station that is about five miles west of Veyo in Washington County, Utah. The project involves recovering waste heat from the compressor station to generate electricity using an energy converter. The waste heat facility would produce up to approximately 7.8 megawatts per hour, and is expected to produce 58,000 megawatts annually based on normal pipeline operations.
The new waste heat oil heater (WHOH) and a portion of the heat transfer fluid (HTF) piping system would be constructed within the Kern River Compressor Station fence line. The Ormat Energy Converter (OEC), substation, distribution interconnection, and associated components would be constructed on approximately four acres of land immediately north of and adjacent to the Kern River Compressor Station fence line.
The project facilities would include waste heat oil heaters, thermal fluid storage, a pumping and piping system (closed-loop systems), a ullage system, a working fluid vaporizer and preheater, a working fluid turbine and generator, a recuperator, an air-cooled condenser, an expansion tank, an emergency diesel generator, a diesel fuel storage tank, substation components, an electrical distribution line, microwave and fiber-optic telecommunication systems, and appurtenant components to support these facilities.
New switchgear components (transformer, relays breaker, etc.) would be constructed and operated within the fenced OEC area to convert the generated electricity to 34.5 kV. A new 34.5-kV distribution line would be installed to connect the new plant to the existing overhead distribution line. To accept this new load to the grid, this overhead line could require reconductoring for a length of approximately 4.5 miles, according to the PacifiCorp d/b/a Rocky Mountain Power interconnection study.
UAMPS’ purposes include the planning, financing, development, acquisition, construction, operation, and maintenance of various projects for the generation, supply, transmission, and management of electric energy for the benefit of its members. UAMPS’ current 45 members include 35 municipalities, one joint action agency, one electric service district, two public utility districts, two water conservancy districts, two cooperatives, one municipal utility district, and one non-profit corporation in Utah and seven other Western states (Arizona, California, Idaho, Nevada, New Mexico, Oregon and Wyoming).
